This is the second Stebel Nautilus horn I have purchased. The first went on my 2002 Aprilia RSVR. The second is going on my 2012 BMW K1300S. The horns that come on these bikes are apologetic; instead of a little "excuse me," you want a "WHAT THE HECK ARE YOU DOING IN MY LANE" kind of response. The Stebel is it. (Posted on 11/12/14)

Finally got my nautilus dual-tone air horn working.This thing is LOUD, however, I did test it with a meter and only got 132 db. Plenty of sound but quite a bit of difference between advertised sound and actual sound.. Would still give it 5 stars. (Posted on 9/27/14)

Whenever I buy a new bike, this is the first item I put on it. It is the best/cheapest thing you can do to increase your safety. Loud pipes help people hear you, but they are loud all the time and create too much animosity among non-riders. This is only loud when you need it to be. And it's much cheaper than new pipes.

The only problem I have ever had with this product is that I can't find a place to install it on my new Triumph Thruxton. I have installed one of these on a Honda ST1300, a Honda CB1000R, a Honda Shadow Spirit and a Suzuki Bandit. Never been disappointed in the performance. (Posted on 8/19/14)

I have been using the Stebel Nautilus horn on my '05 V Strom for about 6 years now....but not the first one I bought....that was about two horns ago. I mount mine on my SW Motec crash bars, in the proper position, ie. straight up and down. The vibration from the motor must be jarring the innards loose because they quit after about a year. Don't do much riding in the rain, so can't blame it on that. They just fall apart. They are great while they work though, real lifesavers. Will try using some rubber strips for padding and see if that extends the life any.To be continued. (Posted on 8/7/14)

I purchased the horn and am glad I did as I now have a real hearable horn instead of the weak sounding one that comes with the motorcycle. Now I can be heard! (Posted on 7/7/14)

I installed the horn and it worked great for about 2 weeks. Now it spins and pumps out air but doesn't make any noise. It actually died on me while in use as a lady was coming over on me. Not a satisfied customer. (Posted on 7/7/14)

Bought it for the bike, separated the compressor from the horn so it was easier to hide. Works wonderful! Now the "enemy" can hear me in traffic. (Posted on 7/7/14)

Seriously loud horn. excellent safety device. BMW '05 Dakar has a tiny horn. get this and save trouble. old horn was in beak of bike, plenty of places to hide wires behind things and keep it neat. use old horn wires to activate new relay. buy the wiring kit for this, save time. (Posted on 9/23/13)
